LOCK.

Specification of Letters Patent.

Patented Sept. 5, 1916.

Application filed February 24, 1914. Serial No. 820,415.

To all whom it may concern Be it known that I, BERNARD I-I. ZIEHLER, acitizen of the United States, residing at Dayton, in the county ofMontgomery and State of ()hio, have invented certain new and usefulImprovements in Locks, of which the following is a specification,reference being had therein to the accompanying drawing.

This invention relates to looks and more particularly to locks which aredesigned for use upon doors of stores, store rooms or other places towhich several persons have access.

The object of the invention is to provide in connection with a lock adevice which will make and preserve a. record of each operation of thelocking mechanism to lock or unlock the door, and will indicate whichone of the several bolt actuating devices was used in so actuating thebolt.

It is a further object to provide a selective recording device whichwill be set up and actuated by the manipulation of that particular boltactuating device to cause a mark indicating a particular bolt actuatingdevice to be made upon a strip of paper or other suitable material.

Further, it is an object of the invention to provide a bolt actuatingdevice which will lvance the record sheet one step upon each operationof the bolt in either direction.

It is further object of the invention to provide a special key actuatedmechanism nani nilating the bolt which will make it very d fiicult ifnot impossible to so alter one key the lock, that it will cause the ofanother key to be produced.

1 also an object of the invention to provide in connection with thisrecording 1 inanipul the operation of the look by any unauthorizedperson in whose hands a key might accidentally or otherwise find itsway. Further, to provide this combination or permutation n echanism witha detent to hold the tumbler actuating devices in their inoperativepositions while the tumblers are being returned to their normalpositions and t1 us prevent the feeling of the combination.

It is also an object of the invention to provide a mechanism of thischaracter which will be very simple in its construction, positive in itsoperation, and which will require no additional act on the part of theperson manipulating the lock in order that the re cording device may beactuated, but in which in recording will automatically and necessarilyaccompany the operation of the bolt.

In the accompanying drawings Figure 1 is a vertical sectional view takenjust inside the front wall of the casing, and showing the mechanism inelevation; Fig. 2 is a sectional view taken just inside the side wall ofthe casing, showing the mechanism in side elevation; Fig. 3 is a detailview of the lock-out disk; Fig. 4c is a detail of the locking arm forone of the tumblers and Fig. 5 is a facsimile of a record produced bythe recording device.

In carrying out my invention I provide a casing forming a main frameupon which the several parts of the mechanism are mounted and whichcasing may be adapted either to be mounted on the face of a door or tobe mounted in a mortise on the edge of a door. Mounted in this casing isa bolt which may be actuated by any one of a plurality of bolt actuatingdevices. These bolt actuating devices may be in the form of permutationdevices, keys, or the combination of keys and permutation devices, andin addition to the device for actuating the look from the out-- side ofthe door I prefer to provide a bolt actuating device, which may bemanipulated from the inside of the door to actuate the bolt to eitherlock or unlock the door, this inner actuating device not being lockedbut being free for manipulation by anyone at any time. Mounted adjacentto the bolt and preferably within the casing is a recording mechanismcomprising a plurality of separately operable marking devices, eachmarking device bearing a different symbol and each symbol indicating oneof the bolt actuating devices. A selective operating mechanism isprovided for actuating that marking device corresponding to the boltactuating device which is being used to actuate the bolt, and thismechanism is of such a character that it will be automatically set upand actuated by the manipulation of a bolt actuating device. Preferablythe record sheet upon which the marks are made is in the form of a stripof paper or other similar material which is fed from a roll into aposition to receive the marks and is automatically advanced step by stepupon each operation of the recording mechanism.

wall of the casing adjacent to the keeper 3 and is provided at its rearend with a slot 5 to receive a pin 6, secured to the rear wall of thecasing or frame and forming a support and guide for that end of thebolt. The movement of the bolt in either direction may be limited in anysuitable manner. In the present instance a pin 7 is mounted in theforward portion of the bolt, limiting its out ward movement while theend of the slot 5 contacts with the pin 6 to limit its inward movement.As has been stated, this bolt may be actuated either from the inside orthe outside of the door. The two operating mechanisms are necessarilymore or less closely connected one with the other, but may compriseseparate parts or may comprise to a greater or lesser extent the sameparts. In the present arrangement of the mechanism the inside actuatingdevice is in the form of a knob 8, rotatably mounted on the front wallof the casing and having an inwardly extending portion 9, to which issecured a plate 10 having two bolt actuating fingers 11 which are spacedsome distance apart. Secured to the bolt 2 and extending between thefingers 11 is a pin 12, the arrangement of the fingers relatively to thepin being such that as the knob is rotated in one direction or theother, one or the other of the fingers will engage the pin 12 and impartmovement to the bolt in the cor responding direction. A spring 13 isshown as interposed between the plate 10 and the frame member andtending normally to rotate the plate 10 in a direction to cause therearmost finger 11 to engage the pin 12. In the present mechanism aseparate operating plate is employed for imparting movement to the boltwhen the latter is actuated from the outside of the door. This plate isshown in the drawings at 14 as mounted close to the rear wall of thecasing and as having spaced fingers arranged to engage the end of thepin 12 projecting beyond the adjacent side of the bolt 2. The plate 14is operatively connected with a key barrel 16 of a key actuated lock 117mounted in the door. This lock, in the essential features of itsconstruction, corresponds substantially to the well known Yale lockwhich has been modified in certain respects to adapt it to its presentpurpose, and these modifications as well as the manner of connecting thesame with the bolt operating plate 14: will be presently described.

Mounted at the casing 1 below the bolt is a recording mechanism havingsuitable devices for marking upon the strip of paper, as aboveexplained. In the present embodiment of the invention the markingdevices are in the form of punches, each of which is shaped to form adifferent mark or opening in the paper. As here shown these punches areindicated at 17 and are arranged in alinement in a supporting block 18,mounted in the casing and extending transversely to the line of movementof the bolt 2. Each punch has a portion extending above the uppersurface of the block 18 and is normally held in its elevated position bymeans of a spring 19. Arranged beneath the sup porting block 18 is a dieor cutting block 20 having suitable openings to receive the respectivepunches and assist in the punching operation. The punch supporting blockand the cutting block are spaced apart a dis tance sufiicient to enablea record sheet which in the present instance is in the form of a stripof paper 21, to be fed between them. A suitable actuating device is provided for imparting operative movement to any one of the marking devicesor punches 17 and means are provided whereby this actuating device willbe set in operative relation with one of said marking devices, and willhave operative movement imparted thereto to actuate that particularmarking device whenever the bolt 2 is moved in either direction. In thepresent type of mechanism this actuating device comprises an arm or cam22 rotatably mounted on a rod 23, rotatably and slidably mounted in thecasing 1 and extending parallel with the series of marking devices 17.In the present instance the arm 22 is held normally in a position tooperate the marking device corresponding with the knob 8 or inside boltactuating device. This marking device in the present arrangement of theparts lies adjacent to the inner wall of the casing, and in order tocause the arm 22 to normally occupy a position in operative relationwith this particular marking device a spring is provided to move theshaft 23 normally toward such in ner wall of the casing. As is hereshown the knob 8 and the inwardly extending portion thereof have alongitudinal bore 2% into which the end of the shaft 23 extends and inwhich is confined a spring 25 which bears against the end of the shaft23. Operative movement may be imparted to the cam arm 22 in any suitablemanner but this movement is controlled by the movement of the bolt 2, sothat an operative movement of the bolt in either direction will cause anoperative movement to be imparted to the arm. I prefer that the armshould be directly con nected with the bolt so as to be positivelyactuated thereby, and in the present embodiment of the invention I haveprovided the arm 22 with an upwardly extending portion 26 having itsupper ends slotted to engage on opposite sides of a pin 15 which iscarried by the bolt, thus causing the arm to move with the bolt wheneveroperative movement is imparted thereto.

Suitable means are provided for causing the setting and operating of theactuating arm 22 for the marking devices when the bolt is actuated fromthe outside. This may be accomplished in various ways. In the presentinstance the bolt is controlled'by a permutation locking device,operating in conjunction with a key which latter serves to throw thebolt, and I prefer that the controlling means for the arm 22 should besuch that the insertion of the key in the lock will properly positionthe same to cause the operation of the marking device corresponding tothat particular key, and that the rotation of the key will then move thebolt and cause the operation of that particular marking device. In thepresent embodiment of the invention shaft 23 is operatively connectedwith the bolt operating plate 14 so that the rotation of this shaft willcause the operation of the bolt, and the arm 22 is so connected with theshaft 23 that it will move with the shaft when longitudinal movement isimparted thereto. In connection with this shaft I have provided a keyoperated mechanism which will impart both movements thereto. As has beenstated this key controlled mechanism corresponds in its main features ofconstruction to the well known Yale lock and I have so shown the same inFig. 2. This lock is so well known that only a brief description of itsmain characteristics will be necessary. It comprises a body portion 117having rotatably mounted therein a key barrel 16, the barrel and casinghaving formed therein a series of diametrical slots 118, a part of eachslot being formed in the barrel and the remainder in the casing or bodyof the lock. A spring pressed tumbler 27 is mounted in each slot andformed in two parts. In order that the key barrel 16 may be rotated andthe bolt of the lock actuated it is necessary that each of the tumblers27 should be so positioned as to cause the line of division between thetwo parts thereof to coincide with the line of division between the keybarrel and the body of the lock. The lines of division between the twoportions of the several tumblers are arranged at different distancesfrom the corresponding ends of the tumblers and in order to properlyposition them the key is provided with a serrated edge as shown at 28,and when the key has been fully inserted in the lock those portions ofthe edge thereof which engage the several tumblers will properlyposition the tumblers as above explained. Rotatably mounted in thecasing 117 is a plunger 29 having a transverse groove 30 in its innerend, which groove is adapted to receive a tongue 31 carried by theadjacent end of the shaft 23. The plunger 29 has an extension 32provided with a recess 33 to receive the end of the key. Consequentlywhen the key is inserted in the key barrel and rotated, the plunger 29and the shaft 23 will be rotated, and by making the keys of differentlength longitudinal movement may be imparted to the plunger and to theshaft 23 to properly position the actuating arm 22 of the recordingmechanism. The length of the key must be exactly determined in orderthat the exactmovement may be imparted to the arm 22, or otherwise theoperative portion of this arm will overlap the adjacent edges of the twoplunger-s and cause both to be operated, thereby indicating on the faceof the record that a key which is otherwise correct has been altered asto its length. In order to prevent the use of a key which is not of thecorrect length I have provided the key barrel 16 and the casing or bodyportion 117 with additional tumblers 34 and have provided the extension32 of the plunger 29 with a serrated edge so arranged that when in anyone of a series of proper positions the tumblers will be moved in theircorrect positions, but if the extension 32 is not in one of these properpositions, as when a key has been inserted which does not correspond inlength with any of the keys belonging to the lock, the tumblers will beimproperly positioned and the barrel held against rotation.

I have also provided means which are preferably directly operated by thebolt for advancing the record sheet step by step upon successiveoperations of the recording devices. In the present instance a recordsheet which, as stated, is in the form of a strip of paper, is fed froma roll 35, supported in the lower part of the casing, and carried acrossthe die block 20 and between feed rollers 36 and 37, one of theserollers being positively actuated to feed the paper forward. In thepresent instance the upper roller 36 has a ratchet wheel 38, rigidlysecured thereto and provided with a pawl 39 to hold the same againstbackward movement. An operating pawl 40 is pivotally secured at one endof a slide bar 41, the upper end of which is connected with an actuatinglever 42. This actuating lever is here shown as having an upwardlyextending tapered nose 43, the inclined edges of which are adapted to beengaged by the beveled edges of a tapered portion 44 on the lower partof the bolt. In the present instance the rear lower corner of the boltis cut away to bevel the same and a transverse V shaped groove is formedin the lower edge of the bolt a short distance from the rear endthereof, thus providing the tapered portion 44. A spring 45 tends tomove the slide bar and actuating lever 43 upward and hold the taperednose thereof in engagement with one or the other of the beveled surfacesof the bolt. Thus when the bolt is moved in either direction thatparticular beveled surface thereof which is in engagement with the noseof the actuating lever will force the lever down to permit the bolt toride over the same and will thereby cause the pawl 40 to advance thefeed roller 36 one step. This feeding movement takes place at the verybeginning of the movement of the bolt and is completed before the operation of the marking devices. After the strip of paper passes the feedingroller any suit able disposition may be made thereof, and in the presentinstance I have passed it through a pair of guide rollers 46 and thenthrough a slot 47 in the bottom of the easing. The guide rollers 46 arenot positively driven and as the paper is fed forward it will accumulatein a loop between the feed rollers and the guide rollers from which itmay be drawn out through the slot when desired.

In the present embodiment of the invention the bolt cannot be thrown bythe use of a key alone but it is necessary to first set the combinationof a permutation lock. To this end I have provided a detent 48 arragedto engage one of a series of detents 49 formed in the bolt 2 and heldnormally in engagement therewith by means of a spring 50. This pawl isprovided with an arm 51 which extends downward and forward to a pointadjacent to the bolt operating plate 10 which has a pin 52 arranged toengage the end of the arm 51 and move the pawl into an inoperativeposition when the knob 8 is operated, thus permitting the bolt to beactuated from the inside of the door without the setting of thecombination. The movement of the pawl 48 to permit the actuation of thebolt 2 from the outside of the door is controlled by a permutationdevice, which in its broader features is similar to that shown anddescribed in Patent No. 1078120 granted to me Nov. 11, 1913. This deviceas shown in the drawings comprises a series of, in the present instancethree, rotatory tumblers, which are indicated by the reference numeral53, and are mounted upon a shaft 54, carried by the casing or frame ofthe lock. Each tumbler comprises a disk having in one portion of theedge thereof a notch 55 and provided in another portion thereof with aseries of notches 56. The notches 56 of each tumbler cotiperaterespectively with stops 5? rotatably mounted on the axis of the tumblersand having radial movement to permit the same to be moved from one notchto the other and a spring 58 acts upon each stop to hold the samenormally seated. To release the pawl from the bolt it is necessary thatthe notches 55 in the several tumblers be brought into alinement toreceive the projecting portion 59 of a controlling lever 60, whichprojecting portion extends across the edges of the several tumblers, andis held outward in its inoperative position so long as any one of thesetumblers is not in perfect alinement with the other. The controllinglever is provided with a nose 61 engaging a similar nose 62 on the hubof the pawl so that the inward movement of the controlling lever willmove the pawl upward and release the bolt. This inward movement isimparted to the controlling lever, when the tumblers are in alinement bymeans of a spring 63 which is of sufficient strength to overcome thespring 50 which holds the pawl in engagement with the bolt. Thus, assoon as the tumblers are brought into alinement the pawl is moved intoits inoperative position and the bolt is free to move.

In order to bring the tumblers into alinement they are all movedrearwardly to bring the stops into engagement with a fixed part of themechanism, such as a rod 64, and then forward movement is imparted tothem one at a time to advance each tumbler the number of steps necessaryto bring the notches 55 into alinement. The number of steps which isnecessary to advance each tumbler depends upon the position of its stop,and by altering the position of one or more stops the combination can bechanged. It will be noted that that portion of each tumbler in which thenotches 56 are formed is of less width than the corresponding portion ofthe tumbler lying behind it and that the numbers for the notches areplaced upon the outer face of each tumbler, thereby enabling the numberson each tumbler to be readily observed and the changing of thecombination quickly accomplished. The tumblers may be advanced one at atime from the outside of the door in various manners, but for thepurposes of the present look I have provided each tumbler with a ratchetwheel 65 which is rigidly secured thereto. Mounted in the upper portionof the casing above the tumblers are a series of slide bars 66corresponding in number with the tumblers, which number in the presentinstance is three. These slide bars are provided with vertical slots 66through which extend pins 67 to guide the same in their movements.Pivotally mounted on the lower portion of each slide bar is a pawl 68arranged to engage the corresponding ratchets 65 on the downwardmovement of the slide bars. Each slide bar is normally held in itselevated position by means of a spring 68. Each slide bar is alsoprovided with an arm 69 arranged to be actuated by a suitable cam orother engaging device to move the slide bar downward against the tensionof its spring. In the present instance I have shown the actuatingdevices as cams 70, there being one of these cams for each slide bar.Each cam is mounted upon a shaft 71 which is mounted in the casing ofthe lock, extends through the door and is connected on the outside ofthe door with a suitable actuating device such as a thumb piece 72. Inthe present instance the cam is so constructed that each completerotation thereof will impart two movements to the slide bar and thepawl, and to this end I have constructed each cam of two disks or plateshav ing mounted between them on diametrically opposite sides thereofrollers 73 which engage and actuate the arm 69 of the correspondingslide bar when the cam shaft is rotated in either direction. Springpressed levers 74- bear upon the peripheries of the respective tumblersto retard their movement and prevent overthrow. In order to return allthe tumblers to their starting points with the stops in engagement withthe fixed part of the frame, I mount a pin 7 5 upon a plate or disk 76which is mounted on the shaft 54. The shaft extends through the door andhas mounted on its outer end a knob 77 by means of which it may beactuated. The bolt can only be operated once upon each setting of thecombination. To accomplish this a disk or throwout tumbler 78 is mountedon the axis of and in the rear of the tumblers, and has in its peripherya notch 80 corresponding to the notches 55 in the permutation tumblers.This throwout tumbler is connected with the rearmost tumbler by means ofa pin and slot connection as shown at 81, to cause the same to be movedinto operative relation with the projecting part 59 of the controllinglever 60 when the other tumblers are set back to their starting points.Thus when the three permutation tumblers have been adjusted to themechanism above described to bring their notches 55 into alinement theyare also brought into alinement with the notch 80 in the throwouttumbler and the lever 60 is permitted to operate. The throwout tumbleris provided in its lower portion with a cut away portion forming ashoulder 7 9 which is so arranged, when the notches 55 are in alinementthat the movement of the bolt to its open position will cause a lug 82,carried by an arm 83, mounted on the bolt, to engage the shoulder andmove the throwout tumbler a distance suflicient to carry its notch 55out of alinement with the other notches, this movement being permittedby the pin and slot connection between the throwout tumbler and itsadjacent tumbler.

To prevent tampering with the lock and the feeling out of thecombination I have provided means for locking the slide bars, whichcarry the pawls 68, in their elevated positions during the returnmovements of the tumblers. To this end I have provided each slide barwith a lug 84 adapted to be engaged, when the slide bar is in itselevated position, by a latch 85 which is pivotally mounted at 86 on thecasing of the lock. Mounted in the rear of the slide bars 66 is asupplemental slide bar 87 having a stop 88 arranged to engage a finger89 connected with the latch 85 and move the same inward, on the upwardmovement of the slide bars 87, against the tension of a spring 90 whichtends to hold the latch normally in its outer position. The slide bar 87is provided at its lower end with a portion which in the presentinstance is provided with a roller 91, arranged to be engaged by thedisk 7 6 which is provided for this purpose with a cam surface, as shownat 92. This cam surface is so arranged that the latch will be actuatedas soon as the pin 7 5 is moved away from its normal position. I haveshown and described the tumblers as disk shaped and as having theadjusting notches formed in recessed portions thereof, but it will beobvious that this construction is incidental to the arrangement hereshown and that the shape of the tumblers is not a material part of theinvention, and if they were made in other shapes than circular or diskshaped it might not be nec essary or desirable to provide the same withrecesses. Such variations to adapt the mechanism to differentembodiments of the invention would require mechanical skill only.

The operation af the lock is as follows. Assuming that the door islocked and the holder of a key wishes to enter, he must first manipulatethe thumb piece 72 to set the combination, then insert the key in thelock and rotate the same. The insertion of the key sets the actuatingarm for the marking devices of the recorder in a position to actuatethat particular marking device corresponding with the key which isinserted in the lock. The rotation of the key then moves the bolt to itsopen position and the bolt carries with it the actuating arm and causesthe marking device to be operated to make a record upon the record sheet21. At the end of the unlocking movement the bolt may be allowed toremain in its open position when the key is withdrawn, as the personopening the door would usually want to enter and take his key with him.The lost motion between the fingers of the actuating plate for the boltpermits the key barrel to be rotated to a neutral position which willpermit of the removal of the key, without disturbing the bolt. Theremoval of the key permits the spring 25 to move the actuating arm 22 toits normal position, and when the party who has unlocked the door hasentered he locks the door by turning the knob 8 which is on the insidethereof. This knob throws the bolt to its closed position and the bolt,which is always connected with the actuating arm 22 regardless of theposition of this arm, imparts movement to this arm to actuate thatmarking device corresponding with the knob. Ihe lost motion between thefingers of the actuating plate for the knob permits the spring 13 tomove the pin 52, which is carried by one of the fingers of this plate,out of engagement with the trip arm 51, thereby permitting the pawl 48to return to locking engagement with the bolt. Should the holder ofanother key wish to enter while the holder of the first key is within,

EOU

the same operation is repeated and the rec- 0rd shows that the door wasunlocked by the holder of key N o. 2 after it had been locked from theinside, thus showing that the holders of the two keys were within at thesame time. When the holder of key No. 1 wishes to leave he turns theknob, which causes the trip arm 51 to be actuated to move the pawl 48from its inoperative position and then moves the bolt to its openposition, again actuating the marking device corresponding with theknob. After passing out the holder of key No. 1 inserts his key in thelook again setting the actuating arm 22 in a position to operate themarking device corresponding with key No. 1, and then rotates the key tomove the bolt to its locked position, again making a recordcorresponding with that key. If the holder of key No. 2 has passed outalong with the holder of key No. 1 this will complete the record, whichwill appear as shown in Fig. 4 where the pea-r shaped mark representsthe knob, the square represents key No. 1 and the dash represents keyNo. 2. If the holder of key No. 2 remained after the holder of key No. 1left, then it will be necessary for him to operate the knob to open thedoor and to use his key to relock it and the record will show theseoperations. If the holder of one key opens the door from the inside topermit the holder of the other key to leave and then relocks the door onthe inside, this will also be shown by the record, which remains in thelock until it is removed by the proper authority at a subsequent time.

It is preferable that some means be provided to prevent the removal anddestruction of records by unauthorized persons. One very simple way ofdoing this is to number the records consecutively. Thus if it is foundthat a record removed from the lock does not follow consecutively afterthe last record previously removed by the person authorized to do so itwill be obvious that someone has removed a record without authority. IAnd as the door must have been locked on the outside after the recordwas thus removed without authority, there will still be some record toshow who had operated the lock and destroyed the record.

While I have shown and described one embodiment of my invention it willbe understood that this has been chosen for the purpose of illustrationonly and that I do not wish to be limited to the details of constructionshown and described, as obvious modifications will occur to personsskilled in the art.
